My invention relates to a curtain rod threading device for hollow curtain rods to insure that the curtain rod may be threaded into the rod receiving channel or hem of the curtain with- 5 out catching at any portion thereof. I am aware that others have provided curtain rod threading devices made of wire having arrow or spiral shaped threadingv outer ends of greater height than the height of the hollow curtain rod so as to l insure that theicurtain rod will not catch in the curtain at the upper and lower surfaces thereof. So far as I am aware, no one has hitherto provided a curtain rod threading device having a flat threading outer end of greater height than said l hollow curtain rod adapted to pierce a curtain rod channel and prevent the top and bottom edges from catching on the top and bottom walls of said curtain rod as the rod is being inserted therein, which at threading outer end first has' 0 its inner end offset laterally in one direction, then extends forward obliquely laterally from inner to outer end to have its outer end oset laterally in the opposite direction to provide lateral eirtensions oiset in opposite directionsirom the inner and outer ends of said threading outer end to prevent the sides of said curtain channel from catching on the side walls of said curtain'rod as said rod is being inserted. l

A 'further object of my invention is to provide such a construction made of a single piece of bent wire constructed so as to spread the channel so that it positively cannot 'catch on the curtain rod as the rod is being inserted and which permits therefore the curtain rod to be guided therein into the most delicate fabric without injury thereto.

Further objects of my invention are to provide a device simple to manufacture which may be quickly attached and detached from the curtain rod and also one which is relatively cheap and durable.

These and such other objects of my invention as may hereinafter appear will be best understood from the accompanying drawing which illustrates embodiments thereof.

In the drawing, wherein like characters of reference generallyyindicate like parts throughout, I0 generally indicates a curtain rod threading device constructedl in accordance with my invention.A

Great diiculty has been experienced in threading the ends of curtain rods through the curtainrod receiving channels or hems of curtains without damage to the fabric. My invention aims to provide a device which will overcome these dimculties and so spread the curtain rod receiving channel or hem I2 so that not only will the top and bottom of the curtain rod I4 be not caught within the top and bottom of ksaid channel but also to laterally spread the channel to prevent the edges on the sides of the curtain rod from also being caught in the side walls of said channel I2. To this end my invention comprises a curtain rod threading device for hollow curtain rods, comprising a at threaded outer end I6 of greater height than said hollow curtain rod I4 adapted to pierce a curtain rod channel and prevent the top and bottom edges of said channel from catching on the top and bottom edges of said curtain rod as the rod is being inserted therein as shown in Figs. 1 and 2, terminating in an inner end I8 of less height, said device also having an inner end 20 to be received by said hollow rod I4, said flat threading outer end first having its inner end oiset laterally in one direction as at 26, then extending forwardly obliquely laterally from inner to outer end as at 22 to have its outer end offset laterally in the opposite direction as at 24 to provide the extensions 24 and 26 offset laterally in opposite directions of said outer threading end of the thickness of the curtain rod to prevent the sides of said curtain rod channel I2 from catching on said curtain rod I4 as said rod is being inserted. While any type of a hollow curtain rod may be employed, I have shown in the drawing, a standard type `of curtain rod having a flat side wall 30 and ends 32 bent inwardly from the opposite top and bottom ends thereof to form an opposite side wall having an open center portion into which the inner end 20 of my device may be readily threaded.

It is obvious, however, that while I have shown my invention in association with a flat curtain rod it 'may be employed for round or other shaped curtain rods with equal facility, and it is obvious that while I have described my invention in regard to height, etc., in the specication and claims as applied to a iiat curtain rod it is immaterial in what position my improved d evice be inserted within the end of the hollow curtain rod,

In the preferred embodiment of my invention shown, I have provided a one piece curtain rod threading device comprising a single piece of wire having a threading loop I6 at the outer end thereof of greater height than said hollow curtain rod adapted to pierce the curtain rod channel I2 and prevent the top and bottom edges from catching on the top and bottom edges of said curtain rod as the rod is being inserted therein, terminating in inner ends I8 of less height and spaced free ends 2D extending rearwardly from said loop inner ends I8 to form an expanding tongue to be received by said hollow curtain rod, the threading loop I6 rst having its inner end offset latrally in one direction as at 26 then extending forwardly obliquely laterally from inner to outer end as at 22 to have its outer end offset laterally in the opposite direction as at 24 to provide the extensions 24 and 26 offset laterally in opposite directions of said outer threading end to prevent the sides oi said curtain rod channel from catching on said curtain rod as said rod -is being inserted in the threading channel I2 whether the device be constructed of wire or otherwise of any Suitable shape. I have shown in Figs. 1 to 5 said loop as having an arrow headed shape or a hollow arrow headed shape if constructed ofwire and provided with a closed outer end 34 pointed to pierce the curtain rod channel I2 and diverging reawvardly to points 36 where its height exceeds the height of the hollow curtain rod to prevent the top and bottom edges of said channel from catching on the top and bottom edges of said curtain rod as the rod is being inserted, from which points 36 it is bent inwardly to form stop shoulders 38 on the top and bottom edges to terminate in inner ends I8 of less height than said points 36. If desired, however, as shown in Figs. 6 and 7. the threading outer end I6' may be of substantially circular shape and if wire is ernployed to provide a susbtantially circular loop of greater height than the curtain rod.

As stated previously, while I have described my improved device in the position it assumes in use with a flat curtain rod it is obvious that my invention functions to spread the curtain rod channel in four planes at right angles to each other and is immaterial in what manner it be inserted in the curtain channel or hem. My device constructed for the at hollow curtain rod as shown in Figs. 1 to 3 may be then inserted in the hem as shown in Figs. 1 and 2 to spread the hem in said four directions to positively insure that no portion of the hem will become caught on the curtain rod.

It is understood that my invention is not limited to the specific embodiments shown and that various' deviations may be made therefrom without departing from the spirit and scope of the appended claims.

What I claim is:

l. A one piece curtain rod threading device for hollow curtain rods, comprising a single piece of wire having a threading loop at the outer end of greater height than said hollow curtain rod, adapted to pierce a curtain rod holding channel ing its inner end offset laterally in one direction,
